India in the 16th century presented a fragmented picture of rulers, both Muslim and Hindu, who lacked concern for their subjects and who failed to create a common body of laws or institutions. Outside developments also played a role in shaping events. The circumnavigation of Africa by the Portuguese explorer Vasco da Gama in 1498 allowed Europeans to challenge Arab control of the trading routes between Europe and Asia. In Central Asia and Afghanistan, shifts in power pushed Babur of Ferghana (in present-day Uzbekistan) southward, first to Kabul and then to India. The dynasty he founded endured for more than three centuries.
